Hmm, that's strange: Your problem sounds too similar to be a different bug.
Could you copy the error message you got? It might be a clue. Also, what
backend are you running?

>>> import matplotlib.pyplot as plt
>>> print plt.rcParams['backend']

Another possibility (longshot) is that your version of `ffmpeg` may not
respect the `-loglevel quiet` flag being passed to suppress output. Maybe
you could try running an `ffmpeg` command with and without that flag to see
if it works.
